This invention relates to improved means or apparatus for drying andconditioning hanks or loops of any fibrous or other materials, such aswoollen, cotton, linen, jute,ha1r,

F and other yarns in machinery or apparatus of the type in which alongitudinal central drv 1g chamber arranged-en framework w n. may ormay not be closed at one end between two longitudinal chambers in whichare placed the heating apparatus, fans and mechanism for imparting therequisite intermittent travelling motion to the poles upon which thehanks or loops are hung.

The machine or apparatus as regards the construction of the framework,the general arrangement of the lon itudinal chambers, the heatingapparatus, the fans placed in the said chamber, and mechanismfor'imparting the required motion to the main movingparts of the machinemay be similar to that described in the U. S. American Letters PatentNo. 881602 grantedto me the Tenth day of March 1908; except the meansfor placing the poles in the machine; intermittently traversing thepoles raising them to a higher level and delivering them arevaried, improved and simplified by eliminating certain portions and providingmeans whereby a rotary motion may automatically be imparted to the polesat one or more stages of their movement. p 7 I In the drawings hereuntoannexed are shown means for carrying the invention into practice. inwhich 7 I Fig. 1 is a part side elevation of the front end of themachine;

Like parts in all the views are marked with similar reference numerals.

1, 1 and 2 are longitudinal compartments. the central one 2 being usedas a drying chamher. In the compartments 1, 1 are inserted a number ofradiators or other heating apparatus 1 the heat from which is circulatedand driven into the drying chamber 2 by fan 1 mounted upon shafts 1provided with driving pulleys 1. To the inner surface of each of thelongitudinal walls 3, 3, of the drying chamber 2 are fixed a number ofrails 4, 4, 5, 5 composed of lengths of angle iron which form horizontalraces,-hereinafter termed the lower races 4, 4, and the upper races 5,5,upon which the poles 6 are caused to intermittently travel. The numberof lower and upper races 4, 4, and 5, 5,

will vary with the number of times the hanks in line 4 of the reference6 are required to pass through the machine before reaching theconditioning chamber 7 of the framework. In the drawings two sets onlyof lower races 4, 4, and upper races 5, 5, are shown at suitabledistances apart and arranged on each of the two inner walls of thedrying chamber 2, but the number of races to be fixed to the walls willrequire to be varied to correspond with the number of times that thehanks are required to be passed throughthe chamber.

The rails which form the upper and lower races 5, 5, and 4, 4, are notof the same length, the upper races 5, 5, being the longer of the two,and they also project a suitable distance beyond the lower races 4, 4,at the front end of the machine. The inner ends of both the lower andupper races 4, 4, and 5, 5, extend to a suitable distance from andwithin the closed end 8 of the framework of the machine.

In the two rails forming the lower races 4, 4, is or are provided one ormore longitudinal gaps 9 at a suitable distance from the closet end 8 ofthe drying chamber 2. Each gap 9 is made of such a length that a rack 10having spur or other teeth 11 on its upper surface may be insertedtherein for imparting a rotary motion to a number-say, two or more ofpoles 6 as they travel over the racks. The ends of the rails-at thegapsare connected respectively to the ends of the rack. The teeth 11 ofthe rack 10 are clear of the inner edge of the lower races, 4, 4, asshown at Fig. 13.

The poles 6 are placed, as hereinafter described, transversely acrossthe drying chamher 2 with each of their ends resting upon the lowerraces 4, 4. The central portion of each pole 6 is made of wood or othersuitabie material and of a square, or round, or other cross section. Oneach end of a pole 6 there is fixed a metal ferrule 12circular in crosssection provid-ed with a number of spur teeth 13 (Fig. 13) formed on itsperiphery at a suitable distance from its outer end. The teeth 13 engagewith the rack 10 and impart a rotary motion to the poles 6 as the l tterare intermittently propelled along the races. The outer end of eachferrule 12 is square in cross section so as to prevent the poles 6rotating when the spur teeth 13 are not in contact with the teeth of arack 10.

At a suitable distance from the closed. end

8 of the drying chamber 2 and fixed to one of the vertical channel irons14 on the outside of each side wall 3 of the drying chamber 2 is abearing 15 for a transverse shaft 16, one end of which projects withinthe drying chamber 2. On the inner end of the shaft 16 is fixed a pulley17 having a numbersay, two or moreof pieces 18 of angle iron fixed toits periphery for causing the poles 6 to travel around with the pulley17.

A suitable guard or guide 19 is provided around and at a convenientdistance from a portion of the periphery of the pulley for aiding inretaining the poles 6 in position. The guard 19 is shown in the drawingsat Figs. 2 and 12 to be a continuation of the lower races 4, 4, beyondthe gap 9, and the upper portion of the said guard is arranged to extenda suitable distance over the upper races 5, 5.

A separate shaft 16, pulley 17 and parts connected therewith areprovided on each side of the drying chamber 2, the outer end of theshaft 16 being carried in a similar bearing 20 to the bearing 15 andfixed to one of the vertical channel irons 21 forming the outer walls22, 22 of the machine.

A rotary motion is imparted to each shaft 16 from any convenient sourceof power to the fast pulley 23 mounted upon the shaft 24 (Fig. 5)carried in suitable bearings fixed to the machine framework. On theshaft 24 is mounted a cone pulley which communicates with a second conepulley (Figs. 4 and 5) employed for communicating motion to theintermittently travelling bars 43 and 44. On the shaft 24 is mounted aworm 25 which gears with a worm wheel 26 mounted upon a transverse shaft27 (Fig. 5).

On the shaft 27 are also mounted sprocket wheels 28, 28 which transmitthe required rotary motion by means of an endless chain 29 to a secondsprocket wheel 30 mounted upon the shaft 16. The outer end of each shaft16 is geared by means of the miter wheels 31 to the longitudinal shaft32. The shaft 32 is carried in suitable bearings 33 fixed to the outerwalls 22 of the machine framework.

An intermittent motion is imparted to the poles 6 as follows At asuitable distance from each end of the lower and upper races 4, 4, and5, 5, and on each side of the drying chamber are a pair of verticalframes 34, 34, 35, 35 (Figs.

12 and 13). Each frame 34, 35 may be made in the form of a casting or inskeleton form built up of, say, angle irons, in which provision is madefor a vertical recess or opening 36 and a horizontal recess or opening37,

both of which are respectively termed the vertical opening 36 and thehorizontal opening 37. In or about the centre of the horizontal recess37 of each vertical frame 34 or 35 is mounted, in suitable bearings 38fixed to the framework of the machine, the

inner end of a shaft 39 which extends through and beyondthe heating andfan chambers 1, l of the machine. On the outer end of each shaft 39 isfixed bevel gearing 39 for connecting it to one of the longitudinalshafts 32. On each of the shafts 39, and in the center of the verticalframe 34, 35, are fixed a pairof cams 40, 41- of different sizes, thelarger cam 40 is arranged to act against the sides 42 of the verticalopening 36 for imparting an intermittent horizontal movement thereto,and the smaller cam 41 acts upon the top and bottom portions of the saidhorizontal opening 37, whereby an intermittent rising and falling motionis imparted to the said frame.

To the upper and lower ends of eachpair of vertical frames 34, 35 whichare arranged respectively at each side of the drying chamber 2, arefixed horizontally, angle iron bars 43, 43, 44, 44, the ends of whichproject a suitable distance beyond each of the said frames. The angleirons 43, 44 at the top and bottom of the vertical frames are connectedtogether by one or more vertical rods or plates 45 which pass throughguide brackets 46 fixed to the walls of the drying chamber 2.

To each of the horizontal bars 43, 44 are fixed a number of fingers 47,48. The said fingers are so fixed to their respective bars that theyproject a suitable distance below the bars 43 and above the bars 44. Thefingers are fixed at a suitable distancesay, for example only, at apitch of six inches, more or lessapart for causingeach pole 6 to beintermittently moved the required distance along their respective racesWhen the vertical frames 34,35, the bars 43, 44 and fingers 47 have beenmoved to their lowest position by the cam 41, the fingers 47 will thenbe behind the peripheries of the ferrules 12 of the poles 6 ready tocause thepoles to travel in the direction of arrow a onthe lower races4, 4, the required distance when the frames 34, 35 are acted upon by thelarger cams 40. Vfhilst the fingers 47 are in engagement with the pole 6on the lower races 4, 4, the upper fingers 48 will then be clear of thepole 6 on the upper races 5, 5, thus allowing the last named poles toremain sta= tionary during the feeding movement of the poles on thelower races 4, 4. Afterwards when the vertical frames 34, 35 have beenraised by the cams 41 for enabling the upper fingers 48 to act uponthe-poles 6, which have been transferred by the pulleys 17 from thelower races 4, 4, to the upper races 5,5, the fingers 47 will then havebeen raised clear of the poles 6 on the lower races 4, 4. The poles 6 onthe upper races 5, 5, are then moved the required distance in anopposite directionthat is, in the direction of arrow Z), to the poles onthe lower races 4, 4, which are then stationary.

lower and upper bars 43, 44 are fixed thereon at or about the samedistance apart, but the fingers 48 on the upper bars 44 are arranged tobe at or about the centre of the spaces between each pair of fingers 47on the lower bars 43.

The poles 6 to be fed to the lower races 2 4, 4, (Figs. 6 to 8) areplaced upon the horizontal portions of angle irons 49, 49 which arerespectively fixed to the framework 14 on each side of the dryingchamber'2, and the said horizontal portions 49 are arranged upon ahigher level than the lower races 4, 4. The said horizontal portions 49are bent at their inner ends 50 to a suitable angle so as to deliver thepoles 6, one at a time, on to the lower races 4, 4. The inclined portionof each of the said angle irons is provided with a guide plate 51 whichis suitably fixed in position by any convenient means.

To an inclined stay 52which may also be formed of angle iron-are fixedbrackets 53, 54. The bracket 53 connects the stay 52 to the upright 14,and the bracket 54 forms the bearing for a short spindle 55 which isfixed at right angles thereto. At the ends of the spindle 55 are fixed apair of levers 56, 57 the lever 56 is curved and its free end-isarranged to pass through a loop 58 which is fixed to the lowerintermittently reciprocating bars 43. The lever 57 is arranged with acurved end 59 which is employed for pushing the pole 6 which has beendelivered on to the lower races 4, 4, into position to be acted upon bya finger 47fixed to the bars 43when the vertical frames 34, 35 and bars43, 44 connected thereto are moved in the direction of pulley 17 whichis employed for moving the poles 6 from the lower races 4, 4 to theupperraces 5, 5. W hen this movement takes place the pushing lever 57alsoprevents the poles 6 falling out at the mouth of the inclinedportions 50 whilst the said intermittent traversing motion is takingplace. The poles 6 are placed by hand on the horizontal portion 49 ofthe angle irons at the feed end of the machine.

When the poles 6 have reached the outer ends of the upper races 5, 5,they will then have passed through the conditioning chamber 7, and theymay either be arranged to be carried in a downward directionas shown atFigs. 1, 9 to 11'- or, if so desired, be carried in an upward directionon to, say, the floor of a story of a building above that in which staysto one of the uprights 14 on each side of the framework of the machineor its drying chamber 2, are employed. To the angle iron guides whichform delivery inclines are fixed, by any convenient means, a number oibrackets 61 at suitable distances apart, which "form bearings for a holow tube 9 62 provided with a number of projecting rods or fingers 63which are fixed to its periphery at suitable distances apart. Betweeneach pair of rods or fingers 63 is fixed a second set 01 fingers 64which are arranged at a different angle to the rods or fingers 63.

It will readily be understood that a rod or finger 64 is placed betweeneach pair of rods or lingers 63.

The rods or fingers 63, 64 act as stops for regulating the descent ofthe poles 6 one at a time. An oscillating movement is imparted to thehollow tube 62 by a. pair of levers 65, 66 which are mounted upon a pin67 carried by a bracket 68 fixed to one of the vertical channels 14 ofthe machine. The end of the lever is turned at a suit able angle to itsmain portion and provined with a slot 69 which engages with a. pin orrod 70. One end of the rod 70 is fixed to the oscillating tube 62. Theend of lever 66 is curved and ertends in an upward direction and passesthrough a loop 71 fined to the u I381 intermittentl' reci rocatin l i obar 44.

If desired the two levers 65, 66 may be formed on one boss 72, orseparately mounted on the pivot pin or spindle 67 fixed to the bracket68.

It will readily understood that there is a similar of lovers 65, 66 andparts connected ther with arranged on each side of the drying chamber 2for delivering the poles 6.

As shown at Fig. 9, the inclined guides 60 are turned horizontally forreceiving the poles 6 after they have passed down the inclined por ionsfrom which they are removed by hand or in an other convenient manner.

When it is required to carry the poles 6 in an upward direction two setsof levers will be necessary, arranged as follows One 01": the sets oflevers is employed for oscillating the tube 62 and a second set oflevers for regulating the movement of the pole 6. hen this is donethehollow tube 62 will require to have a sliding, as well as anoscillating, movement imparted thereto, and in this case the tube 62will be mounted upon a rod 7 3, the ends of which are carried bybrackets 7 4, fixed respectively to one of the uprights 14 ot themachine and to a horizontal portion 7 6 of the upper delivering end or"the incline 60. Two brackets 77,

78 are employed on each side of'the drying chamber 2 and they are fixedto the uprights 14 or" the framework of the machine. The brackets 7 7are arranged to be above the upper races 5, 5, of the machine whichcommunicates with the inclines 60, and the other brackets 78 arearranged at a suitable distance below the said races. On a pivot pin orspindle 79 of the upper bracket 77 is arranged a lever EEO-(made in oneor two parts)-the pendant portion 31 of which is below the upper races5, 5, and it is arranged to engage alternately with pins 82 and 82 fixedto the upper intermittently reciprocating bar 44 to which the fingers 48are fixed. The upper and longer portion of the lever is connected by abar or rod 83 to a double ended lever 84 which is pivoted upon a pin 85fixed to a bracket 86 secured to the undersurface of the incline 60. Theopposite end of the double ended lever 84 is provided with a slot 87 ofany convenient length which engages with a pin 88 secured to the tube62. The said lovers are employed for imparting an oscillating motion tothe hollow tube 62 whenever the intermittently moving part 44 isoperated by the means hereinbefore described.

To the second and lower bracket 78 is pivoted a double ended lever 89having a slot 90 at one end ior engagement with a pin 91 fixed to themoving bar 44. The lower end of the lever 89 is connected to a bar 92,provided with a bifurcated or other end 93, adapted to engage with a pinor pins 94 fixed to a collar 95 which is mounted upon the hollow slidingand oscillating tube 62. The collar 95 is retained'in position by a pairof collars 96, 96, which are fixed to the tube 62 by set screws, orother convenient means not shown in the drawings. The sliding andoscillating tube 62 is also provided with a similar arrangement ofprojecting rods or fingers 63 as previously described. In this instancethe fingers 63 are employed for causing the poles to travel in an upwarddi rection, and steps 97 are provided for preventing the poles 6descending whilst the turning movement is taking place.

The action of the levers 80, S3, 84, 89 and 92 is as follows:

WVhen the fingers 48 of the upper reciproeating bar 44 are in engagementwith the poles 6 on the upper races 5, 5, and the said bars are at theextent of their forward travel. the fingers 63 of the sliding tube 62are then in contact with the poles 6 on the inclines 60, prior to movingthem in an upward direction, as shown at Fig. 15. Upon the fingers 43and bars 44 being moved vertically by the operating cams 4lFig. 12,-totheir lowest position, and then by cams 40 in a horizontal backwarddirection, the operating levers 89 and 92 move the tube 62, fingers 63and the poles 6 on the inclines 60 in an upward direction. The distanceof travel of the poles 6 on the inclines 60 is slightly greater thanthat of the poles on the races 5, 5, that is to say, levers 89 and 92are arranged to move the poles a short distance beyond the front edge ofthe steps 97. Simultaneously with the said slight extra movement of thepoles 6 the pin 82 fixed to the bar 44 engages with the pendant portion81 of the lever 80. At or about the end of the backward travel of thesaid bar 44 the tube 62 and fingers 63, through levers 80, 88 and 84 arecaused to turn out of engagement with the poles G on the inclines 60,the levers 80, 83, 84, 89 and 92 will then be in the positions shown atFig. 15 The said poles on being released slide, the short distancebefore named,down the inclines until they are retained by the stops 97.The bars 44 and fingers 38 are then raised to their highest position andmoved hori zontally forward carrying the poles on the upper races 5, 5,therewith. This movement, by means of levers 89 and 92, returns thesliding tube 62 and its fingers 63 to their lowest position. Themovement for again turning the said fingers 63 into position behind thepoles on the inclines 60 is imparted by means of the pin 82 engaging( ator about the end of the forward movement of the bar 44with the pendantportion 81 of the lever 80, the levers 80, 83, 84, 89 and 92 will thenagain be in the position shown at Fig. 15. The said operations can thenbe repeated de novo.

A convenient form of stop 97-is illustrated at Figs. 15 and 20, whichmay be arranged as follows To or above the upper edge of the incline 60is arranged a plate 98' which extends nearly the full length of the saidincline and is attached thereto by means of a number of hinges 99 whichare fixed at suitable distances apart. On the inner surface of the plate98 are fixed a number of stops 97 which are arranged at distances apartso as to be between the fingers 63. A leaf spring 100 may be employedfor retaining the plate 98 in an upright position. The lower portion ofeach of the stops 97 is inclined at an angle to the inner surface of theplate 98 so as to engage with the ferrules 12 of the poles 6 as theymove in an upward direction. The lower longitudinal edges of the steps97 are arranged to taper and the front end of the said stops projects asuitable distance below the plate 98' for retaining the poles'6 in astationary position.

In some cases in place of the leaf spring 100 a helical spring 101 20)may be employed, and its ends are connected respectively to the hingedplate 98 on each side of the drying chamber so as tc enable the twoplates to be simultaneously returned to their normal position afterbeing acted'upon by the poles 6. The said tapered edge is provided sothat when a pole 6 is being moved in an upward direction by the fingers68, the ferrules of the poles cause the plates 98 to move in an. outwarddirection so that they can travel along the said tapered edges forallowing the pole to pass, and as soon as the ferrule of the latter isclear or the same, the springs immediately return the stops to theirnormal position, thereby retaining the poles in a stationary position,thus preventing them descending whilst the turning movement of the tube62 and fingers 63 is taking place.

In some cases it may be found more convenient to make provision for boththe feeding and turning levers to be arranged above the upperintermittently reciprocating bar 44, as shown at Figs. 16 to 19. Whenthis is done the two brackets 77, 78 will be arranged in suitablepositions above the bar 44 instead of one above and one below it, andthe end of the lever 92 that imparts the sliding movement to the tube 62will be provided with a slotted pendant end 102 which engages with thepin 94 of collar 95. The lever 9-2 is pivoted to an upright 14 of themachine above the upper bar 44.

It will readily be understood that in all cases the above named leversthat impart the oscillating and sliding movement are provided for eachside of the machine.

When it is requiredto dry, condition, and deliver wet yarns by passingthem once throughthe machine, then the hereinbefore named framework isarranged to be open at both ends, in which case the poles with wet hanksof yarn thereon are fed into the machine at one end, then caused totravel through it by the means herein described, and deliverconditionedat the opposite end. When this is done the pulley 17 which transfers thepoles from the lower races 4, 4, to the upper races 5, 5, is dispensedwith, and a conditioning, chamber is provided at the delivery end of themachine. One or two longitudinal sets of races are arranged in each machine, and the drying and conditioning chambers are arranged inlongitudinal alignment.

The action of the machine is as follows The hanks having been arrangedupon the poles 6 are placed by hand upon the horizontal portion 49 andallowed to slide down the incline 50 when the hooked lever 57 will havebeen moved so as to permit the ferruled ends of the poles 6 to pass onto the races 4, 4. The movement of the hooked portions 57 isaccomplished by means of the curved levers 56 being acted upon by thereciprcating bars 43. One pole at a time is admitted on to the races 4,4, and on the return movement of the levers 57 is pushed forward in thedirection of arrow a. This operation is repeated until the poles 6 arecaused to travel by the fingers 47 towards the rear end of the machine.As soon as the teeth 13 of the ferrules 12 come in contact with theteeth of the rack 10, a rotary, as well as a travelling, motion isimparted to each pole6. This rotary and travelling motion continues aslong as the spur teeth of the ferrule are in mesh with the teeth of therack. After a vpole has passed over the racks it is carried forward bythe fingers 47' into a position to be acted upon by one of the brackets18 of the pulley l? by which it is transferred from the lower races 4,4, to the upper races 5, 5. During the said movement of the poles 6 onthe lower races 4, 4, the fingers 48 fixed to the reciproeating bar 44,will be lowered out of engage ment with the poles 6 on the upper races5, 5. The longitudinal movement of the poles 6 on either of the raceswill be, as previously explained, effectedby the cams 40. After thepoles 6 on the lower races 4, 4, have been moved the required distance,the fingers 47 are raised clear by the cam 41, and the fingers 48 areraised so as to be in a position to move the poles 6 on the upper races5, 5. The intermittent longitudinal reciprocating movement is continueduntil the poles 6. in the upper races 5, 5, reach, and pass through theconditioning chamber 7, when they are delivered either in a downward orupward direction as previously explained.

lVhen a drying chamber 2 is provided with a plurality of compartmentsarranged one above the other, then the front ends of the upper races 5,5, of one compartment will require to be connected with the front endsof the lower races 4, 4, in the compartment immediately above it by endguards 19 and pulleys 17.

What I claim is p 1. Apparatus for drying yarn or other textilematerials in hanks or loops having in combination a frame-work dividedinto three longitudinal compartments open at their front and closed attheir rear, the two outer compartments having air fans and heatingapparatus arranged therein, and the central chamber being employed fordrying purposes, a pair of horizontal races fixed at different levels tothe inner surfaces of the longitudinal walls of the drying chamber, aplurality of poles adapted to support hanks thereon placed one at a timehorizontally by h and upon the lower races, each pole having a ferruleat each of its ends adapted to slide on the lower races, and also havingspur teeth on its periphery adapted to engage with spur racks providedon the said races for imparting an intermittent rotary motion to thepoles, means arranged within. the said chamber for intermittentlypropelling the poles along the upper and lower races, the poles on oneof the races remaining stationary when the poles on the other races arebeing moved, means for raising the poles from the.
